Researchers Submit Patent Application, "Method And Apparatus For Performing Wireless Power Transmission On Basis Of Authentication", for Approval (USPTO 20240030753).

LG Electronics Inc. has submitted a patent application for a method and apparatus for wireless power transmission based on authentication. The invention aims to provide a wireless power transmitter and receiver that support authentication through out-band communication, specifically using Bluetooth Low Energy (BLE). The patent application outlines various aspects of the authentication procedure, including message exchanges and negotiation processes. This patent application describes a method and apparatus for performing wireless power transmission based on authentication. The wireless power receiver and transmitter use out-band communication, such as Bluetooth Low Energy (BLE), to authenticate each other. The authentication procedure can be performed using the Logical Link Control and Adaptation Protocol (L2CAP) or the Generic Attribute Profile (GATT) of BLE. The communication/control circuit of the receiver and transmitter perform various steps, including transmitting and receiving authentication messages, to establish a secure connection for wireless power transmission.
